What the *Bleep* happened?!! LOL
 

I put some thought into a new setup made from things I had laying around.

It was time to pair the Mamba Monster with some Monster Tires. Mate the Medusa 36-60-1500kv with the E maxx on 10000mah 4S Lipo.

To insure decent motor temps, a HV Maxx heat sink was used. Works really well too, I might add.

For gearing, I used a 52 tooth Mod 1 spur and a 18 tooth Mod 1 pinion, I made from an original style E maxx tranny input shaft.

This thing will almost do a standing flip! :lol:

Traction out the wazoo! These tires are almost 7 1/2 inches tall.

About 10 minutes into the run, I notice this clicking sound. The tranny has the 2 speed kit installed. When I switched the tranny to low gear, I knew I had just about stripped out high gear.

These 2 speed kits aren't all their cracked up to be. :no:

It would still go, so I figured what the heck. Keep running it and see what kind of runtime I get with all this battery packed on. :tongue:

About 25 minutes into the run, I seen some of the most insane flips. :rofl:

Then It did one more flip, and this is what I walked up on. I thought it was sitting awfully funny!

Ummmm, I think it's time for some upgrades! :lol:

lol sir, looks like you need some UE knucklehead shock towers and GA bulks

wow!!!!! those tires a huge!


Who needs shocks anyways :)

Nice to see the quality of the stock parts is still high :lol:

Nice carnage- I must say though, plastic tranny gears + proper BL power is never going to work for too long, traxxas just refuse to use much metal in their vehicles for some reason :neutral:

You pulled off a double tower, impressive. Lucky you, every time i'd do that, it'd be the bulks

Haha, that's what you get for "sticking" the landing! :lol: The truck must have had some good altitude on that last one.

Look like tires and wheels off of the CEN GST7.7 (or Genesis) and the are huge, but then again so is the CEN truck :intello:

I don't know what the hell you did, but whatever it was I would have paid to see it!

Ahhhh a little shock oil and your back in business. :rofl:

I have a revo with similar sized tires and a NEU 1515 2.5d that also has this "clicking tranny" issue. I've replaced all the gears with Robinson Racing metal gears but have to take it apart again to see what is going on in there..

same to my E-MAXX, but mine was the rear shock tower broken and then the shocks.

A very good reason to start a long journey of hop-up.

Wheels...
 

Those wheels and tires look good on the Maxx. Nice work with the shock towers. It is like I keep saying. Plastic toys were made for boys:rofl:. If you want to drive your truck like a man, then you have to get rid of all that plastic. These trucks look great and the design is a nice piece of engineering, but as long as one uses plastic it will never last for long. If this is any indication of how hard you like to drive, then you need to build your trucks to be "bulletproof". Why waste your time running back and forth with broken plastic parts. RCM hybrid bulk/diffs with hardened HPI lightning gears, and metal tranny gears or a center diff setup is what you have to do. So "Git er done" and have some real fun:yipi:. By the way those batteries look impressive in there:yes:. How were tehy working for you?:lol:

I was thinking, your shocks probably bottomed out before the chassis did because of the huge tires. All that stress had to go somewhere! :oh:

But yeah, alloy towers would solve that problem; then alloy bulks, then alloy diff cases, then alloy arms, etcetera, etcetera..... :lol:

We all love to drive hard don't we? LOL

I'm am VERY impressed with the power of the Medusa Motors. I did not expect it to throw this truck around the way it did. Not that I'm blaming it on the motor. :rofl:

I've really been looking at the Gorillamax G4 chassis.

One problem I have with setups is the very limited space for Batteries. Why can't we cram in an hour of wild runtime?

These batteries are pretty awesome, but they are big. Each one is 2S2P of 5000mah 10C cells. I know the C rating is small, but I believe them to be under-rated somewhat. Even at 10C, this gives 100 amps continous, 150 amps Burst.

It is an hour runtime setup. :yes: I ran for about 20-25 minutes before the come-a-part happened. Each pack was at 7.99 volts when it was over. I did run it pretty hard too. Obviously. LOL

Yes, they did bottom out HARD!

I wonder if there is a way to dramatically increase suspension travel?

Factory setups are configured along with tire size to "belly out" before the shocks bottom out.

I've broken stock shock towers before. They really are not that strong.

I remember one jump where it came down wheels up, didn't hit that hard really, but still broke the rear shock tower.

On the Transmission with the 2 speed kit, I'm sure the secondary output gear is just about gone.

The single speed setup is MUCH stronger IMO. You just have to look at the design.

It's amazing to me just how much the smaller tires spin. This does relieve the drivetrain of alot of stress.

With larger tires that grip, that stress is much greater.

Attach the lower shock mount closer to the chassis (so it compresses less per inch of wheel travel) and use heavier springs/more pre-load. That should help.

Some updates on this setup.

The clicking sound was due to me using too long a screws in the slipper. When I would gag it and make the slipper slip, the screws were gouging the other side of the slipper. Ooops.

I installed a new single speed tranny that I had and continued to change the setup.

After all the shock carnage repair, I changed the gearing again and put the stock tires back on.

I then changed the gearing on the medusa 36-60-1500kv to 22/40. Works great!

Then I decided to get creative with a Mamba Max. I built a little cooling house for it. LOL

I wanted to install a thermistor on the heat sink for fan operation, but couldn't find one that would work, so the fan runs all the time. Heated air exits through holes drilled in the ends of the casing.

I figured it would give some protection also.

A Novak 2700uf cap was added to the power leads as well as a CC UBEC.

This setup runs great. The motor stays cool and the ESC does too.

The 10,000mah 10C 4S setup gives an hour runtime. :yes:

Cool stuff.
 

Hey Sikes I really like the idea of putting the ESC inside a little doghouse like that to control the airflow, and to keep it protected from other eliments. Thats engenious. What motor are you running on that thing? And an hour of run time is great for the average basher for sure. I have a set of those 10K pks as well, but I haven't even used them yet. I hope to put them on my V-twin Dewalt 970 setup for some fun in the next few weeks. I am still waiting on a few things to come in so I can complete the build. I have hardened steel pins comming to make indestructable hinge pins. I am tired of having to fight to remove bent pins from the bulkheads and arms. I am working on the wiring today trying to get it all nice and clean looking like your setup. Nice work Sikeston. I am also making up special harnesses for hooking up dual battery packs. One set of harnesses for running quad packs in paralelle, and one set for running quad packs in series. I really like having a little versatility to try out different power setups. I am finally getting to use my new Hako soldering rig, which was a great buy. Have a good one Sikeston.

That's great. I can come out of the closet now. I play with tupperware too! I did one of the tupperware control units last winter on my ped. I put a couple small fans on the top. One would blow in on the MM the other one would blow out to help circulate the air. I found lots of ways to try and keep my setups out of the snow before I finally believed everyone on how water resistant the mm were. It kept me busy trying though.

Those are cool, and in winter the box looks bad azz for snow, I wish I had 1 but come summer youre going to need a hobby city edf to cool it. JMO

Thank you Jerry.

I thought I would try something different. Most of the time, I'm not all about the bling. I'm about what works and for the longer the better.

The 10K packs are close to the same weight of a 14 cell nimh setup, but give so much more. 100amps continous, 150 amps burst is more than enough. They hardly even get warm.

It's a Medusa 36-60-1500kv. 22/40 Mod 1 gearing is high enough to choke alot of motors, but this one being lower kv, it does fine with it. No cogging at all. The oversized heat sink really takes care of things. I know it's cool out right now, but I believe this setup would do well even if it were 90 outside.

You have a really nice collection Jerry. I ran back through your threads and took a peak. Good Luck with the pins, I feel your pain on trying to fix bent ones when things go wrong.

On the Wiring harnesss, just get you some Deans connectors and some 12Ga. Noodle wire, then use your imagination. LOL Just get the good quality stuff to start with and you won't be disappointed.

There's nothing wrong with being creative! :yes: LOL

Oh cool, I really hadn't thought about the tupperware items. The case I used was something that self-tapping screws came in. LOL I just had to cut it down some. It was much longer than this.

Nice. I'm glad to see I'm not the first one to do this kinda thing. :yes:

I don't think it's going to be that bad actually.

When you disable the internal bec on the mm, you rid yourself of ALOT of heat. It is a linear bec, which means it gets pretty hot doing its job.

The addition of the Novak 2700uf capacitor really helps temps too.

Then we have the fan. (Brain G's nemesis module........LOL) I was tempted to drill holes in the side of the lower casing on the MM. Then match those up with holes in the enclosure. This would force air across the lower part of the power board, the brain board.

The fan pressurizes the box somewhat as long as you don't drill too many holes for the air to exit. With this in mind, just drill holes in the hotspots and the heat will bleed off those areas quickly.

One other thing I like about the box is, it gives you additional surfaces to mount things.

Thank you.
 

Thank you Sikes for the positive comments. The build is comming together nicely and I cannot wait to get the home made hardened steel hinge pins installed. The steel pins should arrive in the next few days, and then I can complete the project and get it up and running. This has been a long time comming for me. Plus the boys are excited to finally see one of my projects completed and running so they can have some fun with it.

On the Wiring harnesss, just get you some Deans connectors and some 12Ga. Noodle wire, then use your imagination. LOL Just get the good quality stuff to start with and you won't be disappointed.

Actually I just removed all of my Deans and sent them to a Pay it Forward birthday boy. I prefer the new TRX connectors myself. Once you figure out the best way to install them they are much more user frinedly in my opinion. I guess my fingers are too big for using the Deans plugs(too small and no grip) espcially if you are trying to get her done in a hurry. The first one turned out pretty good, and I love making stuff like this myself. Three moreto go. Anyway thanks for the comments Sir.

It's not always tupperware. Ever wonder what the top cover on the new stack of cd could be used for?

Thought it might be good for a laugh. It actually was the best one I came up with for the rustler. It fit over the battery and everything and sat flat on the lexan chassis I made. Easy to get into and easy to put on and off. Didn't even need the rubber band. Once I had the lid pinned on it held it nice and tight. I guess last winter was pretty long after looking though a bunch picutes to find these. I even put a wind scoop on the pedes tupperware to keep snow from being blown into it. Man I was bored last winter.

Hilarious.
 

Hey Guy that is hilarious:rofl:. Yes I would say you were definitely bored:oh:. I think that this would qualify for a new one of those "you know your addicted to RC" statements. You know your addicted to RC if you are stealing the wifes tupaware containers to keep snow out of your vehicles electronics:yes:. That is too funny man. I guess you do whatever you have to in order to get out there and play even it the snowfall is ten feet high. Cudoes to you for the "A" effort. Your wheels must be turning in your sleep trying to come up with this stuff, while most of us would be looking out of the window praying that the snow melts soon. Way to go Guy.:yipi:

Nice "mystery machine" lunchbox/container in the top left Guy! You must have all kinds of stuff in that house!
